Our Carbon Steel Hex Bar are crafted from high-grade carbon and alloy steel, boasting exceptional dimensional accuracy, uniform mechanical properties, and superior machinability. Covering key grades such as 1045, 4130, S235JR, they are the go-to choice for parts requiring non-rotational stability—including fasteners (hex bolts/nuts), valve stems, gear blanks, and precision mechanical components. Available in standard hexagonal sizes with surface finishes like black oxide, turned, or polished. Every batch is accompanied by a mill test certificate (MTC), fully compliant with ASTM, DIN, and GB international standards.

Manufactured using precision hot-rolling and cold-drawing processes, our fully automated production line incorporates straightening machines and real-time dimension monitoring to ensure ±0.1mm side tolerance and straightness within ≤0.2mm/m. The system is designed to reliably support both standard specifications and custom small-batch production requirements.

In order to ensure product quality, we will arrange professional personnel to check product quality, packaging, weight, hardness, etc., according to customer requirements of product specifications, looking for high-quality and cheap cooperative factories in China, to provide customers with one-stop procurement services and quality assurance.

Excellent packaging: waterproof paper and plastic film + iron cover + at least three strapping straps + strapping straps fixed on iron or wood pallets can effectively protect products from corrosion and various climate changes during transportation. Generally speaking, we ship from Shanghai, Tianjin, Qingdao and Ningbo ports. We have worked with many experienced shipping companies for a long time to find the most suitable mode of transportation for you.
